Specification of Letters Patent. Patented s e; 28 1920 Application filed August 8, 1919. Serial No. 316,167.

To (all whom it may concern:

Be it known that I, HENRY LAsKo, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Stamping-Machine, of which the following is a 'full, clear, and exact description.

This invention relates to a stamping machine, and aims to provide a device by means of which articles such as fountain pens may have imprinted on their outer surface the name of the purchaser or any other subject matter desired.

A further object of the invention is the provision of a machine which is not limited alone to stamping upon fountain pens but which would be universal in its adaptation and by means of which objects, such as fountain pens, or pencils, of any size may readily be accommodated. A still further object of the invention is the construction of a stamping machine which will quickly be ready for operation when it is desired to use the same and by means of which a firm and neat imprint may be produced upon the outer surface of the object to be imprinted. efe'rence. is had to the accompanying drawings which illustrate one practical embodiment of my invention, and in which Figure 1 is a front view partly in section taken along the line 1-1 of Fig. 2; I

' Fig. 2 is a sectional side view through the machine;

Fig. 3 is a sectional plan view taken along line 3-3 of Fig. 2;

Fig. 4c is a side view illustrating the carriage adapted to receive the object to be stamped; and

Fig. 5 is a sectional view taken along line 5-5 of F ig. 4.

In these various views like reference characters designate similar parts, and the refer ence numeral 1 indicates a base upon which is mounteda pair of standards 2 provided with a groove along their longitudinal inner edges in which is slidably mounted a block 3. Extending between the upper ends of the standards 2 there is provided a fixed crosspiece t formed with a screw-threaded openmg 5.

A screw-threaded rod 6 projects through the opening formed in the crosspiece 4 and enga es the screw threads formed therein. The ower end of the rod 6 is conveniently formed in such a manner as to provide a suitable rotatable connection between it and the block 3, such as, for instance, a reduced portion 7, which is engaged by a certain portion of the block.

Rotatably secured to the block 3 by any convenient means, such as a bolt 8, is a stem 9 which projects through a. pair of spaced disks 10 housing an electrical resistance element l1 and heat-retaining material 12 of any suitable construction. A circular plate 13 bears against the outermost of the disks l0 and is firmly retained in this position by means of a head 14; bearing against its outer face, which head 14 is secured to the outer end of the stem 9.

Conveniently extending around the head 14 is a non-heat conducting cage 15, to the outer face of which there is secured a hand knob 16.

Housed within the plate 13 are a suitable number of dies 17 which project radially to a certain extent beyond the edge of the plate 13 and are held in position by any suitable means, such as, for instance, rings 18.

'fraclr members 24L are mounted upon the.

base 1 and extend inwardly between the standards 2, which serve as a slidable mounting for a carriage, including two end portions comprising side walls 25 and a base 26 supported therebetween.

The central portion of the carriage includes, as indicated in Fig. 5, side walls 25 having their upper ends bent inwardl as indicated by the reference numeral 2 so as to overlap a certain portion of the base 26, the lower ends of such side walls being joined together, as clearly shown in this figure. A rocker member, including arms 28 and a joining handle 29, is pivotally secured to the side walls of the central portion of the carriage, as indicated by the reference numeral 30; and a spring 31 is interposed between the base joining the two side walls of the central portion of the carriage and the underside of the base 26.

Conveniently mounted to one side of the 'a spring 36.

It will now be seen in operation that if it is desired to imprint upon the outer surface of an object, such as a fountain pen, any desired characters, this may readily be accomplished by primarily inserting into the body of the fountain pen a core 37 so as to provide a rigid backing for the body of the pen. The handle 29 of the carriage is now depressed so as to swing upwardly the central portion of the same and permit the positioning of the pen upon the base 26, subsequent to which the handle 29 may be released, resulting in the pen being firmly held against movement by virtue of the overlapping 27 of the side walls 25 of the central portion of the carriage.

Current is now supplied to the resistance element 11, which results in a heating of such resistance element and the heat-retaining material 12, and the transmission of such heat to the plate '13 and its associated die 17.

The pen, prior. to its insertion into the carriage, is preferably alined with the scale 33, and the number of characters to be imprinted upon the same are marked off by means of chalk, or any suitable substance, upon the body of the pen so that the characters will appearin proper alinement and spacing when the carriage is moved accordingly by means of the indicator 35 which bears against the division plate 32, designating the corresponding divisions to those derived from the scale 33.

The dies having been sufficiently heated, the carriage is moved forwardly so that it assumes a position between the standards 2 and in accordance with the scale upon the division plate 32. By rotation of the screwthreaded rod 6, by means of its associated handle, the block 3 is now moved downwardly, and by virtue of theirmounting the heated dies are brought to bear with a proper amount, of pressure upon the upper surface of the utensil to be marked; subsequently the direction of rotation of the screw-threaded rod 6 isjreversed so as to raise such dies out of contact with the surface of the device to be marked.

As clearly shown in Fig. 1, by means of the indicator 38 and the ring 18 upon the plate 13, upon which ring characters corresponding to the characters imprinted by the dies appear, it will now be possible to aline the proper die with the, upper surface of the object upon which an imprint is to be made.

It will be noted in this connection that the plate 13 is rotated by means of the knob 16, and that such plate is held from rotation by means of the detent 22, which offers sufficient resistance to any rotational motion to prevent any accidental movement of the plate 13, but which resistance may readily be overcome upon an extraneous force being exerted upon the knob 16.

Obviously, any number of modifications may well be resorted to without departing from the scope of my invention.

Having thus described my invention, I desire to claim:

1. A stamping machine, including a base, a pair of standards upon such base, dies associated with such standards and movable with respect thereto, means for heating such dies, a carriage adapted to receive the device upon which the imprint is to be made, such carriage comprising side walls, a base between such side walls, and means associated with such carriage for retaining the device upon which an imprint is to be made upon such base.
